Pues hombre, ahí te lo dice bien claro, que no se recomienda usar ese 
modo: 

***
Round-robin bonding (mode 0) with virtualization breaks networking for 
guests. Why? How can I work around it?

Solution

There is no plan to provide a solution for this through a code change in 
the bridging code at this time. However, there is an effective workaround:

When trying to achieve greater throughput with bonding, balance-tlb (mode 
5) or 802.3ad (mode 4) should be used since those modes will drop the 
additional incoming broadcast frames before passing the frames to the 
stack.  The problem described in this article is not found in these 
modes. If fault tolerance is the only concern, active-backup (mode 1) 
will avoid this problem by dropping broadcast frames on the backup 
interface.  Use of those alternative modes is recommended.

Por otro lado, los únicos parámetros distintos que veo en tu 
configuración con la que indican en el artículo son "gateway" (visible en 
el tuyo) y "bridge_ports" (no aparece en el tuyo), el resto parece todo 
igual.
